Lift shaft capable of ventilating by wind power and lift ventilating method

The invention relates to a lift shaft capable of ventilating by wind power and a lift ventilating method. The lift shaft is provided with a new air pipeline and an air exhausting pipeline. A new air port is arranged corresponding to a position of a floor and the upper part of a lift car. When the lift runs, a lower exhaust blower stops running. A new air shutter in the lift car is started facing to wind based on the running direction. Air flow with ascending air supplying flow and descending air exhausting flow is formed in the internal part of the lift car, so that energy consumption is saved and respiratory tract infection of passengers and bad influence of odor are effectively prevented. The shortcomings that the lift shaft is damp and the lift car is stuffy are overcome. Therefore, the method disclosed by the invention can be widely applied to ventilation of lift shaft and lift car and the lift shaft can be manufactured in an industrial, standard, universal and serial manner. The invention belongs to the
